Liquid ejecting head and liquid ejecting apparatus

Abstract

There are provided a plurality of nozzles arranged in a first direction; a first piezoelectric element; a second piezoelectric element; pressure chambers in each of which a pressure for jetting liquid from each of the nozzles is applied when the first piezoelectric element is driven; and detection chambers in each of which a residual vibration of the pressure of the liquid applied in each of the pressure chambers is detected by the second piezoelectric element, and, in a plan view, a width of a second active portion in the first direction is larger than a width of a first active portion in the first direction, the second active portion being an active portion of the second piezoelectric element, the first active portion being an active portion of the first piezoelectric element.
